A good & simple way to address things

GPS co-ordinates and map grid references can be confusing and difficult to remember/transcribe at the best of times, and this is where what3words comes to the fore - it has a simple 3-word address for every 3m X 3m square on the earth’s surface.

3-word addresses will never replace GPS co-ordinates or map grid references - they are not designed to. But they are designed to provide a simple addressing system for places that can’t be easily addressed by existing systems, such as:

Where to meet your friends when going to a football match or picnic in the park,
Which track to turn at when walking or 4WDing in the bush,
Where emergency services can find you when you injure yourself on the beach.
You can also have fun with the app by setting up treasure hunts, car rallies, etc.

Much easier than coordinates

A brilliant app which allows the pin-pointing of a location.
Use it to identify where you are at a concert, when camping or even to have items delivered.
So simple even youngsters can use it.
So accurate that it can easily be used to locate lost or injured people or broken down vehicles.
A real winner!

what3words is AMAZING!

This is the best innovation in addressing and location accuracy ever! I love it ♥️
Navigate “down to the spot”, not the “near enough” you get from traditional addresses. Highly recommended. Also try the 3WordPhoto App; it is awesome!
